I ran across a straight B&S tenor the other day that was from the GDR days of manufacturing. I know nothing related to a model, bore size, etc., and I can find very little about B&S horns in general on the interwebs. There appear to be a few positive B&S references here in the forum but I'm guessing that those are of more recent manufacture (post reunification).

Has anyone had any experience with these GDR production horns? Good, bad, ugly? (cue Ennio Morricone...)

Thanks!!

It's .525 bore.

They made three models. All of them are problematic. It's better to get rid of it.
